Description
The CMX90A702 is a highly linear medium power
amplifier operating in Frequency Range 2 (FR2)
from 26.5 to 29.5 GHz, addressing the needs of
5G New Radio (NR) band n257 and n261.
CMX90A702 is a three-stage GaAs MMIC
amplifier delivering +25 dBm (0.3 W) of output
power at 1 dB gain compression, 21 dB of small
signal gain and +32.5 dBm output third order
intercept (OIP3). RF ports are matched to 50 Ω
with an integrated DC blocking capacitor at the
output.
The MPA is easy to monitor and control with an
on-chip temperature-compensated RF power
detector and fast-switching enable circuit.
Using an enhancement mode (E-mode) pHEMT
process ensures only positive supply voltages are
required, thus making single DC supply operation
possible.
